Some estimates put the first human settlements in the Amazon at 32,000 to 39,000 years ago. Since that time, Amazon people have developed lifestyles that are well integrated with the benefits and constraints of rainforests.
An estimated 7-10 million Amerindians (the term for American Indigenous peoples) lived in American rainforests, half of them in Brazil, at the time of European arrival. When Pizarro arrived in Peru, more land was under cultivation and more food was being produced in the Andean region than today.
Answer:
The option C would be a true statement
Pull-apart rift zones are generally associated with a divergent plate boundary.
<u>Explanation:</u>
In geology, rifts are those linear zones where lithosphere is getting pulled apart. Divergent plate boundary, also named as extensional boundary or constructive boundary is a linear characteristic that exist in between both the tectonic plates that tends to move away from each other.
Major rifts can be found alongside the central axis of mid-ocean ridges, where lithosphere and new oceanic crust is created between two tectonic plates in the path of a divergent boundary.
When the two plates pull apart, general faults or breakdowns are developed on both the sides of the rifts and the central blocks start to slide downwards thereby initiating the earthquakes.
The Himalayas Mountains provide a natural barrier between India and the rest of Asia. I hope this helps!!!
